In a colony, there are 100 APL families and 50 BPL families. Each APL and BPL family got blankets equal to 20% and 68%, respectively of total number of families (APL + BPL) in the colony. Find the difference between total number of blankets received by APL and BPL families.
Total number of families in the colony = 100 + 50 = 150 Number of blankets received by APL families = 100 x 0.20 x 150 = 3000 Number of blankets received by BPL families = 50 x 0.68 x 150 = 5100 Required difference = 5100 - 3000 = 2100
